CORDING ATTACHMENT FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented J an. 11, 1910.

Application filed March 12, 1906. Serial No. 305,524.

To all whom it may concern:

Be it known that I, ALBERTINE P. DAY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Cording Attachments forSewing-Machines, of which the following is a specification.

The object of this invention is the production of a device forfacilitating the operation known as cording, said operation consistingin insertinga cord in a fold of cloth and securing it in place by a rowof stitches through the double thickness of cloth at one side of thecord.

In the accompanying drawings Figure l is a perspective view, on anenlarged scale, of a cording attachment embodying the features of myinvention, said cording attachment being shown in place upon thepresserfoot of a sewing machine. Fig. 2 is a side elevation, partly insection, of said cording attachment. Fig. 3 is a sectional view throughsaid attachment taken on the plane of dotted line 3 3 of Fig. 2. Fig. 4is a fragmental top plan view of the corder.

The embodiment herein shown of my invention comprises a guide member 1having a guide edge 2 along which the cord travels, said guide memberbeing provided with means of attachment to the presser-foot of any ofthe standard sewing machines. In this instance said attaching meanscomprises an upwardly extending ear 3 at the forward end of the guidemember 1, said ear being formed integral with said guide member andhaving an opening 4 therein to receive the toe a of the presser foot 6.At the rear end of the guide member 1 and integral therewith is anupwardly extending ear 5 provided at its upper end with a clamp bar 6.Said clamp bar forms the fixed member of a clamp 7 for securing theguide member 1 to the shank c of the presser foot I), the other memberof said clamp consisting of a clamp bar 8. The clamp bars 6 and 8 aresecured together by means of two screws 9 adapted to engage threadedopenings 10 in the opposite ends of the bar 6.

To space the guide member 1 away from the presser foot Z) so that thereshall be sufficient room for the materials between said foot and thetable of the machine, I provide a lug 11, in this instance formedintegral with the guide member 1 and extending upwardly therefrom, saidlug having at its upper end a horizontal portion 12 adapted to lie incontact with the under side of the presser foot.

The needle cl is reciprocated in the opening 0 of the presser foot andpasses just inside the guide edge 2 of the guide member 1. said guidemember being cut away to provide a notch 13 in said guide edge toreceive said needle. The forward portion of the guide edge 2 ispreferably cut away as at 2, and one side of the ear 5 is cut away at Sin order to permit the operator to hold the cord in proper positionrelative to the needle as the cord is fed forward, thus causing the lineof stitches to lie close to the cord. As indicated in Fig. 4, the middleportion of the guide edge 2 is somewhat in advance of, or ratherprojects to one side of, the end portions of said guide edge, therebypermitting the work to be turned before reaching the needle and afterpassing it, when making curved or angular lines of stitching. The lowerends of the ears 3 and 5 are curved, as shown in Fig. 2, to permit theresult mentioned.

If desired, the corder may be provided with a finger 14 pivotallyconnected at one end with the ear 3 by means of a screw 15 andyieldingly pressed against the goods by a coiled spring 16 interposedbetween said finger and the under side of the guide 1. The object of thefinger 14 is to keep the cord from slipping underneath the guide 1.

In use, the corder is attached to the presser foot 5 by inserting thetoe a of said presser foot in the opening 4, the clamp 7 havingpreviously. been opened by swinging the clamp bar 8 upward as shown indotted lines in Fig. 8. The clamp is then closed and the bars 6 and 8drawn up by the screws 9 to clamp the corder firmly in place. The cloth0c is folded over the cord 1 and fed toward the needle in the directionindicated by the arrow in Fig. 2, the cord traveling along the guideedge 2, and the needle reciprocating just inside said edge in the notch13.

I claim as my invention.

1. In a cording attachment for sewing machines, in combination, a guidemember; an ear at each end of said guide member, one of said ears beingperforated to receive the toe of the presser-foot of the machine, andthe other car being provided with a clamp bar; a second clamp bar; andmeans for detachably securing said clamp bars together.

2. In a cording attachment for sewing machines, in combination, a guidemember; means at one end of said guide member for securing it to thepresser-toot'ol the machine; a stationary clamp bar at the opposite endof said guide member; a pivoted clamp bar; and means for securing saidclamp bars together.

In a cording attachment for sewing machines, in combination, a guidemember; an car at one end of said guide member, said ear beingperforated to receive a portion of the presser-toot of the machine; astationary clamp bar at the opposite end of said guide member; a pivotedclamp bar; and means for securing said clamp bars together.

l. In a cording attachment for sewing machines, in combination, a guidemember having a guide edge at one of its outer sides along which thecord is arranged to travel, the middle portion of said guide edge beinglocated to one side of the end portions thereof, said guide memberhaving an upwardlycurving ear at each end, the forward portion of saidguide edge, and one side of the rear ear, being cut away.

In a cording attachment for sewing machines, in combination, a guidemember having a guide edge at one of its outer sides along which thecord is arranged to travel, and a needle notch in said edge, the rearend of said guide member being rounded, whereby the work may be turnedto one side shortly after passing tne needle; and means for attachingsaid guide member to the presser-foot of the machine.

(5. In a cording attachment for sewing machines, in combination, a guidemember; means for attaching the ends of said guide member to the underside of said presserfoot of the machine; and an upwardly-extendingmember on said guidemember between the ends thereof adapted to spacesaid guide member from said presser-foot.
